  444. argument instead of a const uint8_t *buf / int buf_size pair.
  445. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  451. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  452. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  453. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  454. PIX_FMT_BGR32_1 are now macros.
  455. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  456. Re-sort the enum PixelFormat list accordingly.
  457. This change breaks API/ABI backward compatibility.
  458. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  461. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  462. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  463. The Mersenne Twister PRNG implemented through the av_random* functions
  464. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  465. instead.

  467. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  468. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  469. and av_fifo_realloc2.
  470. In addition, the order of the function arguments of av_fifo_generic_read
  471. was changed to match av_fifo_generic_write.
  472. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  473. applications, they may not use sizeof() or directly access members.
  474. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  475. Introduce a new metadata API (see av_metadata_get() and friends).
  476. The old API is now deprecated and should not be used anymore. This especially
  477. includes the following structure fields:
  478. - AVFormatContext.title
  479. - AVFormatContext.author
  480. - AVFormatContext.copyright
  481. - AVFormatContext.comment
